The plugin fully supports Elementor.
So, to show reviews on your product pages, just make sure you add the WooCommerce Tabs widget to your product template and it will automatically be loaded there.
Moreover, if you want to display the reviews in any other place on your website, you can use the widget YITH Advanced Reviews List from YITH menu in the Elementor panel and configure it with the number of reviews, pagination, and product ID.
YITH WooCommerce Points and Rewards allows you to create a points-generating system in your shop so that your users can be encouraged to come back to your store to get rewarded.
The integration with YITH Advanced Reviews will make sure that every review posted through this plugin will be regularly counted so that you can get extra points according to the conditions set up in the Extra Points tab.
With YITH WooCommerce Review For Discounts, customers can leave a review and the system will automatically send an email with a coupon code to the customer, so they can benefit from a discount on the next purchase.
The integration between these two plugins allows sending a discount to customers posting a review of the purchased products by relying on YITH WooCommerce Advanced Reviews engine.
You will only need to install and activate both plugins and configure them separately.
For further details about YITH WooCommerce Review for Discounts settings, please refer to the official documentation.
